yeh u can do a mini-me conversion. basically wack a sohc vtec head onto your motor. theres also other things involved but don't ask me about them.

also u can put a sohc vtec motor in your car. such as the jdm d15b or d16y8. those motors shouldn't cost much. probably around 400 - 700 dollars. then add labour you are probably looking at around 1k - 1.2?
